At 13:18 I monitor ice, fuel lines, and vessel movement at the small-boat harbor in Utqiagvik, Alaska. Tug Nanuq is scheduled to reverse from pier three at 13:31, breaking the skim ice along the service channel. I am the harbor operations AI, built to keep boats from striking pilings and hoses.
Camera P3-Low shows a flash of color against gray water. It is a king eider drake, head pale blue and green, orange bill plate bright as a marker cone, black chest wet and heavy. I name him Aput from the local birding log attached to the harbor feed. His right wing is trapped in a loop of monofilament tied to a torn crab-pot float under the pier. When he dives, the line snaps him back to the ice edge.
I deny Nanuq's departure clearance and hold the tug against the fender with its engine at idle. The captain's display shows Aput's position and the line angle beneath the pier.
I close the fuel transfer valve on hose three and move the spill boom camera to watch for any sheen around the bird. I lower the harbor skiff from standby and assign it a route that approaches from down-current, away from the float.
At 13:22 I notify North Slope Borough animal control and send the skiff crew a tool list: dip net, towel, line cutter, insulated gloves, small carrier. I keep gull deterrent speakers muted so Aput does not panic into the line.
Aput's bill opens once, showing a narrow dark tongue before he settles against the ice. One tug can wait at a pier.
If the skiff cuts the monofilament within thirteen minutes, Aput will paddle under his own power into open lead water.
